Application filed June 16, 1.915. Serial No. 34,449.

lo all 'whom z't may concern l clamping jaws.

Be it known that l, CHARLES Ronin, a citizen of the United States,residing at Cambridge, in the county of Isanti and State of Minnesota,have invented certain new and useful Improvements in Stump- Pullers; andl do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled inthe'art to which it appertains to make and use the same. A

j This invention relates to devices for pulling tree stumps out oftheground; and it consists. in the novel construction and combination ofthe parts hereinafter fully described andclairned. l

' ln the drawings, Figure 1 is a side view of stump pulling devicesconstructed accordingto this invention, and showing the clamp grippingthe rope. F ig. 2 is a side view of the clamp, showing the jaws open.Fig. 3 is an end view of the clamp.

These devices are used by connecting them to two tree stumps 2 and-which are conveniently near together, and they are constructed so thatmuch loss of time in adjusting the length of the pulling rope or cable lis saved. lThe pulling rope or cable e is attached at one-end to thestump 2, and its other end portion is woundnpon any suitable drum orwinding mechanism which is operated in any "approved manner. A cord 6 isfastened around theother tree stump 3, and has a ring Tat its free end.A slidable clamp is provided for connecting the ring Z to the pullingrope or cable 4. j This clamp is formed of two parallel clamping jaws 8and 9 having their adjacent edges 9 grooved so as to engage with therope. Levers .12 are provided and are arranged in a series parallel toeach other and crosswise of the These levers are pivoted to the jaw 8 bypins 14, and" to the jaw 9 by p ins l5. Bars 16 are pivoted to theprojecting free end portions of the levers 12 by pins 17, and these barshave a loop' 18 at one end which engages with the ring 7.

The pulling drum or other winding naech-u anisrn is secured to anyconvenient anchor stump which is strong enough andwhich is not shown.The cord 6 and the pulling rope l are fastened around any two stumpswhich are conveniently located and which are not too large for theanchor stump. The clamp or take up is placed upon the pulling rope Jl byhand, the jaws being slid along the rope l, or the rope el being slidthrough the jaws, asA foundl convenient and until the partsv assume thepositionsshown in Fig. l and the cord 6 is taut and the jaws are infrictionalengagement with the rope 4. The portion ofthe rope l betweenthe clamp or take'up and the stump 2 need not be taut, and it is usuallynot in line with the portion of the rop-e 4 between the clamp and thepulling drum. The clamp is Aclamped on the rope 4 anywhere convenient soas to pull two selected stumps.

By the use of this device two stumps can be pulled at each pullingoperationA of the drum, and much time, usually wasted in pulling inslack lpulling rope, is saved.

What I claim is:

In stump pulling devices, a pulling cable for attachment to a stump, aring provided with means for securing it to a second stump, and a clampcomprising two parallel jaws for engaging the pulling cable, a series oflevers pivoted lto the jaws and arranged crosswise of them, and a barpivoted to the projecting free end portions of the levers and having aloop atl one epd which engages with the said'ring.

In Vtestimony whereof I have alixed my signature.

CHARLES RODN.
